MEncoder: selected video_out device is incompatible with this codec

I am using h263enc script for encoding mpg2 recordings created by udpxrec (udpxy).

Everything was working fine for last two years, but now I get following error:

The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

I am not sure if IP-TV Provider changed codec.

Any idea? Thank you.

Re: MEncoder: selected video_out device is incompatible with this codec

Not much information given.

[mpegts @ 0x7f353f841740]decoding for stream 3 failed

Can't find the audio stream info in the transport stream.

[mpegts @ 0x7f353f841740]Could not find codec parameters for stream 3 (Audio: mp3 ([6][0][0][0] / 0x0006), 0 channels, s16p): unspecified frame size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

Allow ffmpeg to probe farther into the stream to find info with something like.

ffmpeg -probesize 1000000000 -analyzeduration 100000000 -i movie.ts

Looks like it's mpeg2 video and mp3 audio. What are you wanting to reencode into?

Here is an example for h264 video and copy the audio.

ffmpeg -i movie.ts -probesize 1000000000 -analyzeduration 100000000 -c:a copy -c:v libx264 -b:v 2500k Output.avi

I stopped using mencoder several years ago due to it not working very well. It uses ffmpeg for it's backend anyway.

If you want more answer, give more info.

Re: MEncoder: selected video_out device is incompatible with this codec

ffmpeg is working with no problem, I will focus on this one.

h264enc script is probably using ffmpeg only for decoding. Here is content of scripts bactch file:

nice -n 10 /usr/bin/mencoder "$i" -o /dev/null  -passlogfile "~/.h264enc/job19156/${i%.*}.log" -demuxer lavf     -nosub    -vf softskip,harddup           -oac pcm -ovc x264 -x264encopts pass=1:bitrate=1000:nointerlaced:force_cfr:frameref=3:mixed_refs:bframes=10:b_adapt=1:b_pyramid=normal:weight_b:weightp=1:direct_pred=spatial:aq_mode=2:me=hex:subq=6:nombtree:chroma_me:trellis=1:cabac:deblock:no8x8dct:partitions=p8x8,b8x8,i4x4:nofast_pskip:nodct_decimate:threads=auto:keyint=250:keyint_min=25

Re: MEncoder: selected video_out device is incompatible with this codec

You've left out a whole lot of info like what you are doing, How you are doing it, and what your script looks like.

So if I understand this, you are capturing a tv broadcast transport stream to file, then you want to reencode that .ts video to something else?

I see that udpxy is a MPEG-TS recording tool. I've never used it. Does it alter the stream at all? Also how are you capturing this stream? Do you have a tv tuner in your computer? If so you can simply dump the stream that's coming out of the tuner to file with no alteration.

I'll tell you what I do know. Use these examples for your setup.
If you have mencoder installed then you must have mplayer. You'll need ~/.mplayer/channels.conf configured.

mplayer dvb://WABC -dumpstream -dumpfile Output.ts

Or you can simply zap a channel (linuxtv-dvb-apps)

azap -r -c ~/.mplayer/channels.conf WABC

Then cat the stream to file.

cat /dev/dvb/adapter0/dvr0 > Output.ts

mplayer /dev/dvb/adapter0/dvr0 -dumpstream -dumpfile Output.ts

ffmpeg -i /dev/dvb/adapter0/dvr0 -c copy Output.ts

Or you can use mpv, the syntax is different.
That will give you a Output.ts that you can reencode to another format to save space.

If you are set to use udpxy then start with posting the output of

ffmpeg -i YourVideoFile.ts

To see what that file looks like.
Then post your script that you are using.
If it's a normal mpeg transport stream with audio and video then you can change containers or reencode it to another audio and or video format.

PES packet size mismatch with mpeg2/ac3 can usually be solved when reencoding mpeg.ts with

ffmpeg -i vid.ts -bsf:a aac_adtstoasc

Sometimes you will need

ffmpeg -i file.ts -copytb 1

I can tell you how to manipulate these stream with ffmpeg, I think that mencoder is lacking, it has video audio sync problems.
Also I think that using harddup and softskip with mencoder is mutually exclusive. You want to capture all frames or you want to skip some.

nice -n 10 /usr/bin/mencoder "$i" -o "/destination//${i%.*}.avi"  -passlogfile "~/.h264enc/job19156/${i%.*}.log" -demuxer lavf     -nosub    -vf softskip,harddup               -oac pcm -ovc x264 -x264encopts pass=2:bitrate=1000:nointerlaced:force_cfr:frameref=3:mixed_refs:bframes=10:b_adapt=1:b_pyramid=normal:weight_b:weightp=1:direct_pred=spatial:aq_mode=2:me=hex:subq=6:nombtree:chroma_me:trellis=1:cabac:deblock:no8x8dct:partitions=p8x8,b8x8,i4x4:nofast_pskip:nodct_decimate:threads=auto:keyint=250:keyint_min=25

I don't think that you need all of that.

If your dead set on using mencoder then start with something simple and go from there.

mencoder movie.ts -oac mp3lame -lameopts cbr:br=192 -ovc x264 -x264encopts bitrate=2500 -vf crop=710:480:4:10,harddup -ofps 24000/1001 -o output.avi

Solve the errors that you get.

I am using udpxy for direct recording multicast stream from IPTV (without set-top-box).

Ffmpeg encoding is working fine. I will not bother with mencoder anymore.

Thank you very much for extensive info.
