#3533(avformat:new): RTP should have payload type 33 when used with MPEGTS
#3533: RTP should have payload type 33 when used with MPEGTS ----------------------------------+--------------------------------------- Reporter: nunojpg | Type: defect Status: new | Priority: normal Component: avformat | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- When RTP is sending a MPEGTS payload it should report it properly. Otherwise the clients require a SDP, which is completely unnecessary. The correct RTP payload type is 33 - MP2T - MPEG-2 transport stream Video. {{{ nuno@ground3:~$ ffmpeg -i Desktop/sample1.mp4 -f mpegts rtp://127.0.0.1:5004 ffmpeg version N-62130-g8348bd1 Copyright (c) 2000-2014 the FFmpeg developers built on Apr 4 2014 17:04:57 with gcc 4.7 (Ubuntu/Linaro 4.7.3-1ubuntu1) configuration: --enable-libx264 --enable-gpl --enable-libfaac --enable- nonfree libavutil 52. 73.100 / 52. 73.100 libavcodec 55. 56.108 / 55. 56.108 libavformat 55. 36.101 / 55. 36.101 libavdevice 55. 11.100 / 55. 11.100 libavfilter 4. 3.100 / 4. 3.100 libswscale 2. 6.100 / 2. 6.100 libswresample 0. 18.100 / 0. 18.100 libpostproc 52. 3.100 / 52. 3.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Desktop/sample1.mp4': Metadata: major_brand : isom minor_version : 0 compatible_brands: isom3gp4 creation_time : 2013-08-15 12:05:34 Duration: 00:00:40.13, start: 0.000000, bitrate: 17062 kb/s Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080, 16934 kb/s, 29.88 fps, 30 tbr, 90k tbn, 180k tbc (default) Metadata: creation_time : 2013-08-15 12:05:34 handler_name : VideoHandle Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 123 kb/s (default) Metadata: creation_time : 2013-08-15 12:05:34 handler_name : SoundHandle Output #0, mpegts, to 'rtp://127.0.0.1:5004': Metadata: major_brand : isom minor_version : 0 compatible_brands: isom3gp4 encoder : Lavf55.36.101 Stream #0:0(eng): Video: mpeg2video, yuv420p, 1920x1080, q=2-31, 200 kb/s, 90k tbn, 30 tbc (default) Metadata: creation_time : 2013-08-15 12:05:34 handler_name : VideoHandle Stream #0:1(eng): Audio: mp2, 48000 Hz, stereo, s16, 128 kb/s (default) Metadata: creation_time : 2013-08-15 12:05:34 handler_name : SoundHandle Stream mapping: Stream #0:0 -> #0:0 (h264 -> mpeg2video) Stream #0:1 -> #0:1 (aac -> mp2) Press [q] to stop, [?] for help frame= 1204 fps= 57 q=31.0 Lsize= 12626kB time=00:00:40.33 bitrate=2564.5kbits/s dup=5 drop=0 video:10918kB audio:626kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 9.366050% }}} {{{ nuno@ground3:~$ ffplay rtp://127.0.0.1:5004 ffplay version N-62130-g8348bd1 Copyright (c) 2003-2014 the FFmpeg developers built on Apr 4 2014 17:04:57 with gcc 4.7 (Ubuntu/Linaro 4.7.3-1ubuntu1) configuration: --enable-libx264 --enable-gpl --enable-libfaac --enable- nonfree libavutil 52. 73.100 / 52. 73.100 libavcodec 55. 56.108 / 55. 56.108 libavformat 55. 36.101 / 55. 36.101 libavdevice 55. 11.100 / 55. 11.100 libavfilter 4. 3.100 / 4. 3.100 libswscale 2. 6.100 / 2. 6.100 libswresample 0. 18.100 / 0. 18.100 libpostproc 52. 3.100 / 52. 3.100 [rtp @ 0x7f200c0008c0] Unsupported RTP version packet received0/0 [rtp @ 0x7f200c0008c0] Unable to receive RTP payload type 65 without an SDP file describing it Input #0, rtp, from 'rtp://127.0.0.1:5004': Duration: N/A, bitrate: N/A Failed to open file 'rtp://127.0.0.1:5004' or configure filtergraph }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/3533> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

Replying to [comment:1 thovo]:
> Your cmd line is wrong. It explicitly requests for an mpeg TS as output
- not an RTP output stream.
Actual ouput: RTP carrying MPEG-TS.
Actual payload type: not 33.
Bug.
The cmd line being eventually wrong does not change that this demonstrates
a bug. It might not produce the result I would expect though.
But what would be the right cmd line? If I don't explicitly set it to
MPEG-TS then it is streaming a naked video over RTP, while I want it to
stream video and audio encapsulated MPEG-TS with RTP.
